From 3bd6d6540dc62121a978f783a7e73d61ea00a007 Mon Sep 17 00:00:00 2001 From: Baolin Liu Date: Thu, 20 Aug 2026 17:05:02 +0800 Subject: ntfs3: add allocation tracepoints Add ntfs3 tracepoints for allocation operations. This adds trace events for attr_allocate_clusters(), attr_set_size_ex(), and attr_data_get_block() to help observe cluster allocation, size changes, and block mapping activity.
